Musannaf Ibn Abi Shayba 27:730

Yazid ibn Harun narrated to us, he said: Shu'bah informed us, from Qatadah, from Anas, from Usayd ibn Hudayr, that the Messenger of Allah (may Allah bless him and grant him peace) said to the Ansar: "You will see after me selfishness [in the distribution of worldly goods]." They said: "So what do you command us?" He said: "You must be patient until you meet me at the Basin (al-Hawd)."
